I have Verizon...I turned on my phone this am to have a new icon and it wants me to do some update??

I had a Pearl for close to a year and never had this. I asked a few at my office that are on BB phones, not the same as mine, but not one person got this today? I have asked a few people and no one is sure. I am afraid to open this up since I am not certain that its legit. haha..

Update:
okay so I finally started this process...I have not added anything and all my personal stuff is on the SD card. I had it from the Pearl and transferred it over to this phone as it has more storage space then what came with the storm...

Its telling me there is not enough space to download it and it wants to clear personal data space? does this mean its going to kill stuff on my SD card? I havent hit okay yet as I cant loose anything on it.

Seems like the phone should be able to handle this download since I have not added anything to the phone.

My free device memory is 878.5Mb out of a total 879.2Mb. Yet it still gives me the 'delete old data' message. Can I trust these numbers, or is the OTA loader giving me a false error? I even pulled my SD card, in case that was interfering with things.
